[b][color=indigo]I've been told if one uses a darning egg in the toe when doing the Kitchener Stitch it helps eliminate the bunny ear.
I just put the needle down through the last stitch into the sock, turn the sock inside out, give a little tug and then weave in the end. Works really well for me.
The boxy look depends on the kind of toe you used, too. If you are decreasing on both sides up to about 8 sts on two needles and then Kitchener, it'll look boxy. But not bad when you wear them.[/color]
